Matt would it be possible to keep a diary or something like that about your experiances with your new set-up re: heat etc over the next couple of weeks...it's very, very intresting.
I'm in the process of rebuilding my static system and have just bought 2x pulse proportional thermostats and then getting a couple of ibcs etc, etc...but the time to find out this information is now..i.e the winter conditions.
Hope you'll be able to help.
Cheers
Dave.
